I-IP Yezinga Lokuvikela

1. Kusho ukuthini izinga lokuvikela i-IP?

Izinga lokuvikela le-IP (Ingress Protection) liwukuhlukaniswa kwamandla okuvikela uthuli nokungangeni manzi kwemishini kagesi okuchazwe yi-IEC 60529 ejwayelekile yamazwe ngamazwe. Liqukethe i-“IP” elandelwa izinombolo ezimbili: inombolo yokuqala imelela izinga lokuvikela uthuli (0-6), kanti inombolo yesibili imelela izinga lokuvikela amanzi (0-9K). Uma inombolo iphakeme, kulapho ukuvikelwa kuqina khona.

2. Kusho ukuthini inombolo yokuqala (ukuvikelwa kothuli)?

- IP0X: Akukho ukuvikelwa

- IP1X: Ukuvikelwa ezintweni eziqinile ezingaphezu kuka-50mm (njengengemuva lesandla)

- IP2X: Ukuvikelwa ezintweni eziqinile ezingaphezu kuka-12.5mm (njengeminwe)

- IP3X: Ukuvikelwa ezintweni eziqinile ezingaphezu kuka-2.5mm (njengamathuluzi)

- IP4X: Ukuvikelwa ezintweni eziqinile ezinkulu kune-1mm (njengezintambo ezincane)

- IP5X: Ivikela uthuli – ayikwazi ukuvimbela ngokuphelele ukungena kothuli, kodwa uthuli aluthinti ukusebenza okuvamile kwedivayisi

- IP6X: Ayinawo uthuli ngokuphelele – akukho uthuli olungangena

3. Lisho ukuthini inombolo yesibili (engangeni manzi)?

- IPX0: Akukho ukuvikelwa

- IPX1: Isivikelo emanzini aconsayo aqondile

- IPX2: Isivikelo emanzini aconsayo nge-engeli engu-15°

- IPX3: Isivikelo emvuleni (fafaza ngaphakathi kwebanga elingu-60°)

- IPX4: Ukuvikelwa emanzini agelezayo (noma iyiphi indlela)

- IPX5: Isivikelo ekufakweni kwamanzi (umlomo wesivalo ongu-6.3mm)

- IPX6: Isivikelo ekufakweni kwamanzi okunamandla (umlomo womlomo ongu-12.5mm)

- IPX7: Isivikelo ekucwilisweni emanzini isikhathi esifushane (ukujula kwamanzi kwemitha eli-1, imizuzu engama-30)

- IPX8: Ukuvikelwa ekucwilisweni emanzini okuqhubekayo (izimo ezichazwe umenzi, ngokuvamile zingcono kune-IPX7)

- IPX9K: Isivikelo ekushiseni okuphezulu kanye nokufuthwa kwamanzi ngomfutho ophezulu (kufanelekela izimo zokuhlanza njalo)

4. Yiziphi izimo ezivamile zohlelo lokusebenza lwezinga le-IP?

- IP40: Izinto ezivamile zangaphakathi (i-TV, i-router)

- IP54: imishini engangenisi ukuchaphaza (izinto zasekhishini, izibani zangaphandle)

- IP65: ayivimbeli uthuli futhi ayifuni ukufuthwa ngamanzi (ikhabhinethi yokulawula yezimboni, ukuqapha kwangaphandle)

- IP66: Ukuvikelwa ekufakweni kwamanzi okunamandla (imishini yasolwandle, amakhabethe angaphandle)

- IP67: Ingacwiliswa isikhathi esifushane (amadivayisi aphathekayo angaphandle, amawashi ahlakaniphile)

- IP68: Ukucwiliswa isikhathi eside (imishini yokuntywila, amakhamera angaphansi kwamanzi)

5. Uyini umehluko phakathi kwe-IPX7 ne-IPX8?

I-IPX7: Izimo ezilungisiwe (ezicwiliswe emanzini ayi-1 imitha imizuzu engama-30). I-IPX8: Izimo ziqinile kakhulu, kodwa zinqunywa umenzi (njengamamitha ama-5 okujula kwamanzi amahora ama-2). Qaphela: I-IPX8 ayihambelani ngempela namazinga angaphansi kwe-IPX7 futhi idinga ukuphawulwa ngokwehlukana.

6. Ingabe izinga lokuvikela liphezulu, kungcono?

cha. Ukuvikelwa okuphezulu kuvame ukusho ukuvalwa okujiyile kanye nokulahlekelwa ukushabalalisa ukushisa, okwandisa nezindleko kanye nobuningi. Ukukhetha kufanele kusekelwe endaweni yokusetshenziswa yangempela: i-IP40 yanele imishini yangaphakathi; i-IP54 noma ngaphezulu iyadingeka ekuvikelweni kwemvula yangaphandle; i-IP67 noma ngaphezulu iyadingeka ekucwilisweni kwamanzi okungenzeka.

7. Uma umkhiqizo ubhalwe ukuthi IP67, ungasetshenziswa ngaphansi kwamanzi?

Ingacwiliswa isikhathi esifushane (ngaphakathi kwemitha eli-1), kodwa akukhuthazwa ukuthi isetshenziswe emanzini ashisayo, emanzini olwandle noma endaweni ethintekile ngamanzi. Futhi ikhono lokungangeni manzi lendandatho yokuvala lizoncipha ngemva kokuguga, ngakho-ke kunconywa ukuthi uyihlole njalo.

8. Ungayigcina kanjani imishini yokuvikela ye-IP nsuku zonke?

- Gcina izivalo zihlanzekile ukuze ugweme ukuguguleka kwamatshe

- Qiniseka ukuthi yomile uma ushaja noma uxhuma noma ukhipha i-port

- Sula ngokushesha ngemva kokucwiliswa emanzini bese uhlola ukungena kwamanzi

- Gwema umthelela oqondile wokushisa okuphezulu kanye nokugeleza kwamanzi okucindezela okuphezulu

9. Isifinyezo

Ngokukhethaamavalvu ebhabhathanefuthiamavalvu esangongokuhambisana nezincazelo zezinga lokuvikelwa kwe-IP kanye nokwenza ukuvalwa nokugcinwa kwansuku zonke,I-TWSAma-valve ka-'s anamandla okumelana nothuli futhi asebenza kahle futhi afaneleka ezimweni ezahlukahlukene zamapayipi ahamba ngothuli.
